pH and pOH Strong Acids and Bases

Question 1

ph and pOH Relationships

Answer 1

pH = - log[H+].

pOH = - log[OH-].

Question 2

Molarity of Strong Acids

Answer 2

• Molarity is equal to [H+] for monoprotic acids.
  0. 10M HCl -> 0.10 M [H+] + 0.10M Cl-.
• Sulfuric acid is only strong diprotic acid.
  0. 10M H2SO4 -> 2 (0.10M) H+ + 0.10M (SO4)2-.

Question 3

Molarity of Strong Bases

Answer 3

• Molarity is equal to [OH-] for monobasic bases.
  0. 023M NaOH -> 0.023M Na+ + 0.023M OH-.
• Formula unit for dibasic bases:
  0. 023M Ca(OH)2 -> 0.023M (Ca)2+ + 2(0.023M) OH-.
